Connecting Phones via SIP

This article contains information for your system administrator on how to connect your phone devices to the babelforce network.

Most IP deskphones and other telephone devices support SIP. Typically if you have deskphones already, they will allow you to connect to babelforce SIP accounts already. Usually the devices will allow configuration through the telephone keypad itself, through a web browser or with a configuration server (via TFTP/XML settings). We do recommend configuration via web-browser directly if you only need to configure a small amount of devices. Alternatively we can provide provisioning services for the most common devices.

Below are the default settings for SIP clients to connect with the babelforce platform and details of how to ensure your network supports telephony through babelforce.
